Yes I killed with about 7 people from my guild. It probably would have been impossible with full LFR. No one seems capable of interupting their own amber explosion so the last phase when there are multiple constructs out will be pretty hard.

Haven't downed amber shaper yet. P2 and P3 are a nightmare, amber explosions going off, constructs not getting interrupted, P3 with a bunch of constructs up is a shit show. People are killing the constructs instead of the boss, it's just a mess

Wiped like 10+ times on this, mainly because most dps just tunnelvisioned boss. Once couple of us were able to cinvince dps to nuke the constructs it went down right away. If you nuke the constructs down fast enough the players who dont have an idea what to do with it aint that big of a problem. In p3 the healing seemed a bit intesive tought.
